SIR MICK JAGGER may have shown at Glastonbury that he can still rock it on stage – but Rod Stewart insists he is a better singer than the Rolling Stones front man.

And Rod, 68, joked about poaching 66-year-old Stones guitarist Ronnie Wood to reform their band The Faces as soon as Sir Mick, who is 70 this month, decides to hang up his microphone for good.

In a wide-ranging new interview, Rod also expressed doubts about Scottish independence.

The singer said: “I’d like to return with The Faces. Ronnie and I talk about it, and when the Stones finish – Mick is several years older than me – we’ll have a window of opportunity, if we’re not on Zimmers.

“Mick’s a fine blues singer – but technically not as good as me.

“He’s made the best of what he’s got. But I don’t think he could do standards – he may not want to.”

Although born in London, Rod is fanatical about Scotland and a fervent supporter of Glasgow-based Celtic Football Club.

But on the prospect of Scotland voting to leave the UK, he said: “I hope it’s not a lot of kids thinking Braveheart.

“I’d hate to see the Union broken after all these years, and I don’t think it will happen.” Rod has called his Los Angeles home Celtic House.

He’s made the best of what he’s got. But I don’t think he could do standards – he may not want to.”

He said: “That’s because of my Edinburgh-born dad, I suppose.

“There may be three or four pints of Scottish blood in me, tartan pride.

“It’s always been a spiritual home, but as I don’t live there I shouldn’t comment on Scottish independence.

“If it’s good for the Scots, I’m happy.”

Rod also revealed in his Radio Times interview that he suffers from regular bouts of depression.

But he said that his wife, Penny Lancaster, helps him recover quickly. He explained: “My black dog days, as Churchill said. Penny understands and calls it my ‘period’ because it happens about once a month. She stands in front of me, dances and I’m out of it.”

Rod said it must be love with third wife Penny, 42, because he lets her park his Ferrari.

He admitted: “She’s so much better at it than me. I don’t mind if that sounds wimpy.”

Asked if he fancies becoming Sir Rod, the singer said: “If my time comes, it will. If it doesn’t, I’m not bothered. Are you kidding? I never expected a CBE.”
